AI Technical Summary

Technical Problem

The lack of molecular markers and detection technologies that can specifically identify the gloss of eggplant peel in the current technology leads to low selection efficiency, long cycle and high cost in the eggplant breeding process.

Method used

A pair of InDel molecular marker primers (SEQ ID No. 1-2) was developed to identify the gloss of eggplant peel. Combined with a kit and PCR amplification technology, genotyping was performed by detecting the size of PCR product fragments, enabling early identification of eggplant peel gloss.

Benefits of technology

It improves the efficiency of eggplant breeding selection, shortens the breeding cycle, reduces breeding costs, and achieves an accuracy of over 80%, making it suitable for identifying the peel gloss of eggplant throughout its entire growth period.
